Started playing this with @Goafer last night and while I think we both like what the game is, we did start to find the multiplayer aspect very annoying almost immediately. Three times we attempted to do the first quest where you go dig up a treasure chest on a starting island to learn what to do and three times we were killed and our boat sank because some idiots just seemed to want to camp at those beginning areas.
I just can't believe that Rare didn't design the game better so you can get to know what you are doing first before all the troll tossers come out and start ruining it. If we couldn't even complete the first quest then something is wrong.
